I’m certain those are expired by now. Why risk blindness. Are you this dumb with other things?
Glasses don’t expire.
Exactly. Glasses don’t expire. Really old glasses send to have material that would degrade but newer glasses don’t. So assuming you had certified glasses from 2017 and do not have any holes, you are fine.
The chemicals or whatever on the glasses dries out over time and they expire.
Again...nope.
Are you some kind of scientist? I bet you went to trump university.![]()

Dumb pinhole camera question. Does the aluminum foil do anything? It's just there because it's an easy material to poke a hole though, right?
It needs to be thin as well.
Why?
